How to Prevent Computer Eyestrain
怎樣避免電腦引起的視覺疲勞
Computer eyestrain can hurt productivity, but it's easy to prevent if you take a few precautions.
Steps 步驟
STEP 1 Turn down the lights 將亮度調(diào)低
Close the blinds and turn off extra lights to reduce glare.
Use an anti-glare screen or computer hood if you can't reduce the light in your office.
If you're stuck with a CRT monitor, set the refresh rate as high as possible to reduce flicker.
STEP 3 Look away 時不時轉(zhuǎn)移一下視線
Look out a window or down a hall. Break up computer work by focusing on a distant object every twenty minutes.
STEP 4 Blink more 多眨眼
Blink to keep your eyes moist. Blink 10 times, slowly, every half hour.
STEP 5 Use a copy stand 使用復(fù)制架
Use a copy stand and place it next to your monitor to reduce the distance your eyes must travel between page and screen.
Make sure printed materials are well lit, but don't shine a lamp on the screen or in your eyes.
STEP 6 Use computer glasses 選用計算機眼鏡鏡片
Use computer glasses, which are designed specifically for the distance between your eyes and the computer screen.
Computers with Braille displays are available for the sight-impaired.
